»Amazon AMI Data Source

Type: amazon-ami

The Amazon AMI data source will filter and fetch an Amazon AMI, and output all the AMI information that will be then available to use in the Amazon builders.

Note: Data sources is a feature exclusively available to HCL2 templates.

Basic example of usage:

data "amazon-ami" "basic-example" {
    filters = {
        virtualization-type = "hvm"
        name = "ubuntu/images/*ubuntu-xenial-16.04-amd64-server-*"
        root-device-type = "ebs"
    }
    owners = ["099720109477"]
    most_recent = true
}

data "amazon-ami" "basic-example" {    filters = {        virtualization-type = "hvm"        name = "ubuntu/images/*ubuntu-xenial-16.04-amd64-server-*"        root-device-type = "ebs"    }    owners = ["099720109477"]    most_recent = true}

This selects the most recent Ubuntu 16.04 HVM EBS AMI from Canonical. Note that the data source will fail unless exactly one AMI is returned. In the above example, most_recent will cause this to succeed by selecting the newest image.

»Configuration Reference

filters (map[string]string) - Filters used to select an AMI. Any filter described in the docs for DescribeImages is valid.
owners ([]string) - Filters the images by their owner. You may specify one or more AWS account IDs, "self" (which will use the account whose credentials you are using to run Packer), or an AWS owner alias: for example, amazon, aws-marketplace, or microsoft. This option is required for security reasons.
most_recent (bool) - Selects the newest created image when true. This is most useful for selecting a daily distro build.

»Output Data

id (string) - The ID of the AMI.
name (string) - The name of the AMI.
creation_date (string) - The date of creation of the AMI.
owner (string) - The AWS account ID of the owner.
owner_name (string) - The owner alias.
tags (map[string]string) - The key/value combination of the tags assigned to the AMI.

»Authentication

The authentication for Amazon Data Sources uses the same configuration options as Amazon Builders. To learn more about all of the available authentication options please see Amazon Builders authentication.

Note: The authentication session started by a data source is separate from any authentication sessions started by an Amazon builder. Users are encouraged to use variables for defining and sharing configuration values between datasources and builders.

Basic example of an Amazon data source authentication using assume_role:

data "amazon-secretsmanager" "basic-example" {
  name = "packer_test_secret"
  key  = "packer_test_key"

  assume_role {
      role_arn     = "arn:aws:iam::ACCOUNT_ID:role/ROLE_NAME"
      session_name = "SESSION_NAME"
      external_id  = "EXTERNAL_ID"
  }
}

data "amazon-secretsmanager" "basic-example" {  name = "packer_test_secret"  key  = "packer_test_key"
  assume_role {      role_arn     = "arn:aws:iam::ACCOUNT_ID:role/ROLE_NAME"      session_name = "SESSION_NAME"      external_id  = "EXTERNAL_ID"  }}
